Application of materials in desalination water tanks of thermal power plants

Posted on by

The working principle of thermal power plants or nuclear power plants is still essentially boiling water. This water requires a relatively high level of cleanliness:

indicator name Requirement value (Runing) detection method core meaning
Conductivity (25 ℃) ≤0.1 μS/cm Conductivity meter method (GB/T 6908) Reflect the total amount of ion impurities in water to avoid corrosion of equipment
Hardness (calculated as CaCO₃) ≤0.1 μmol/L Complexation titration method (GB/T 6909) Prevent scaling (CaCO₃, Mg(OH)₂ deposition)
Silicon dioxide (SiO₂) ≤20 μg/L Molybdenum blue spectrophotometric method (DL/T 502.2) Prevent the accumulation of silicon scale on turbine blades, which may affect efficiency
Iron (Fe) ≤10 μg/L Phenanthroline spectrophotometric method Prevent iron oxide deposition and avoid corrosion fatigue
Copper (Cu) ≤3 μg/L Atomic absorption spectrophotometry Prevent copper ion catalyzed corrosion and protect precision components
PH value (25 ℃) 6.5-8.5 PH meter method (GB/T 6904) Maintain water quality stability and reduce corrosion risks
Dissolved Oxygen (DO) ≤5 μg/L Sodium indigo disulfonate spectrophotometric method Prevent aerobic corrosion (Fe → Fe²⁺+OH⁻)
Total Organic Carbon (TOC) ≤200 μg/L Combustion oxidation - non dispersive infrared method Avoid the decomposition of organic matter to produce acidic substances

One of its components, the core function of the power plant desalination water tank, is to store and buffer "desalinated water" (used for boiler feedwater, turbine cooling, etc., with extremely high requirements for water purity, and no impurities or rust pollution allowed)

The anti-corrosion principle of nano explosion-proof materials: After curing, a seamless and high-density integrated protective layer is formed, completely isolating the corrosion of the carbon steel water tank substrate by desalinated water (high-purity, weakly corrosive), air, and trace impurities, avoiding substrate corrosion and pitting; At the same time, this material has extremely strong chemical stability, is resistant to water, weak acid and alkali, does not react with desalinated water, and does not release harmful substances, meeting the purity requirements of power plant water quality.

  • Since the birth of the airplane, as one of the symbols of human social progress, its extremely fast speed has brought humanity into the true era of the global village.As an important transportation vehicle, the performance of airplanes is of concern to all of us, including safety performance.
  • Aircraft are generally subjected to the following types of stresses:Tensile stress, compressive stress, torsional stress, shear stress, bending stress.
  • The following image shows the C919 wingStatic test site
  • Applicable location Describe

    notes
    aircraft Nano explosion-proof materials are sprayed: the two components are instantly mixed and sprayed onto the surface of the sprayed object through pressure and heating: Maximize aircraft static testing.
    or Its advantage is that it can achieve 100% integration of the sprayed items. It can wrap the entire sprayed object into a whole and improve the object's protective ability by 300%. (As the thickness increases, the protective ability can be further improved) It can effectively reduce the side effects caused by high-speed vibration of the aircraft and prevent the aircraft from falling apart.
    helicopter This characteristic determines its important role in the aviation industry.

Application of Cashred Nano Explosion Protection in the Petroleum Industry

  • Petroleum is the blood of industry and the foundation of modern society. Almost everything in our lives is inseparable from the shadow of oil. Due to the unique nature of oil,Storage and transportation of oilWe are constantly paying attention to corrosion, which is always present. This affects the lifespan of the carrier for transporting oil: oil pipelines. Research has shown that:
  • ·Nearly 50% of pipeline leaks are caused by internal and external corrosion;
    ·Local corrosion accounts for 70% -90% of corrosion accidents;
    ·For gas transmission, over 20% of leaks are caused by corrosion;
    ·90% of corrosion damage occurs within 10% of the time.

The Cashred nano explosion-proof series products are particularly suitable for use inMilitary Field.It can enhance the combat capability of the troops and enhance the protection ability for soldiers on the battlefield and important military targets of our side.Especially in ship applicationsIt has a wide range of applications, such as wear-resistant and anti-corrosion of ship decks and ro/ro ship decks, as well as significant effects on anti bubble corrosion of ship propellers. Even applied in areas such as ship bottom protection.

cavitation erosion(also known as cavitation) is a special form of wear and corrosion. It occurs in environments with high flow rates of liquid and pressure changes, such as the operating environment of pump impellers. A simple understanding can be:Sharp movement generates a strong pressure difference, which in extreme cases approaches vacuum and forms bubbles. The decrease in pressure leads to accelerated evaporation, with water vapor inside the bubbles and intense agitation. The pressure of water is very high and quickly occupies the vacuum; So repeated.It can be seen that the performance requirements of materials are extremely strict, which seriously limits the choice of materials for propellers.

Cashred nano explosion-proof materialCan effectively solve the problem of cavitation corrosion. Further expanding the field of material selection can further improve the overall quality and performance of ships.
